All variables from $IN->param() into an array?

Hi....does anyone know how you would pass all of the variables from $IN->param() into an array? I have tried several ways....of which none have worked. The reason I need to do this, is to pass all the data from the input, and enter it into forms. I really dont wanna have to manually enter 50+ fields, with their names and values Unsure

Cheers for any help :)

Enter it into forms how?....if you mean as tags then you want a hsahref not an array.

my $input = $IN->get_hash;

For an array (I forgot to tell you) I'd do:

my @values = values %{$IN->get_hash};

Sorry, should have explained better. I need to put them into an array, ready for using in a LSQL template call...

That's what I meant in my first reply. If it is for a template you need a hashref.

Mmmm..I have;

Code:
    my $values = $IN->get_hash; 

    print $IN->header() unless defined;  
    Links::SiteHTML::display('ecard_preview', $values );

Its not giving an error, but simply a blank page Unsure

Am I doing something wrong?

Yea.

This isn't doing what you think it is. What are you trying to determine is defined or not?

So what would do that then? (print the header, only if defined) ?

Eugh...found the reason it wasn't printing! I was missing a 'print' before the Links::SiteHTML Crazy

Stupid or what!

GT::CGI handles that automatically anyway.

You can't just use "defined" in the way you did - see the perldoc for defined.

http://www.perldoc.com/...od/func/defined.html

...so basically the first sentence should tell you that the way you have it, defined is checking whether $_ is defined or not.
